Maintenance Scheduling System
This is a planned schedule for cleaning of sewer lines that are highly susceptible to root intrusion, grease, and various debris. The frequency of cleaning these sewers is determined by their cleaning history with the goal of preventing sewage overflows.

Cleaning
Numerous crews clean and maintain 1,500 miles of sewer main lines on a daily basis in a variety of ways. Power rodders remove roots and other obstructions using a machine that spins various cleaning tools through lines; highly pressurized water trucks clean grit and grease accumulation from sewer mains; and a high volume vacuum removes grit and debris from sewer lines. The homeowner is responsible for maintaining the side sewer.

Closed Circuit Television/Locating
When a problem area in a main line is identified, a video camera with a locating device attached to it is pulled through the line. Necessary repairs to underground sewers are then pinpointed at the street level through live, remote television monitors.

Construction
Construction crews are able to make repairs in the streets and easements using heavy equipment and hand tools.

Emergency Service Crews
CCCSD has an emergency on-call service crew that will respond any time, day or night. If the blockage is in the main sewer, the District crew will take corrective actions. If the problem is in the homeowner's side sewer, they will be notified. Obtain emergency response by calling 925-933-099. Our crews respond to emergencies within 30 minutes and non-emergencies within 45 minutes.

Overflow Prevention Devices (OPD)
An OPD can save you from the very unpleasant and often costly experience of a sewage backup into your home. Click here for more information on where CCCSD's responsibility ends and the property owner's begins, as well as how an overflow prevention device works and where you can purchase one.

Fats, Oils, and Grease (FOG) Program
CCCSD administers a FOG program, specifically aimed at restaurants, to reduce the amount of grease that might enter the sewer system and clog pipes. Depending on the size and type of business (restaurant, bakery, cheese factory, yogurt shop, etc.), CCCSD requires installation of a grease trap or interceptor.

For more information about the FOG Program, to report a problem, or to obtain a copy of the District Code, Chapter 10.32, please call (925) 229-7169.

For oil or sand discharge information, call (925) 229-7288.

User Feedback Survey

To ensure that CSOD crews provide high quality service, CCCSD distributes a User Feedback Survey to residents who request sewer maintenance or repair service. The survey is taken very seriously by CCCSD and follow-up action is taken under these circumstances:
